Predicting global killer whale population collapse from PCB pollution
Killer whales ( Orcinus orca ) are among the most highly polychlorinated biphenyl (PCB)–contaminated mammals in the world, raising concern about the health consequences of current PCB exposures. Using an individual-based model framework and globally available data on PCB concentrations in killer wha...
